Grow light question

labergstarted grow question 2 years ago

I notice a decent drop off in PAR as my meter moves away from center. I have a 2x2 tent and am thinking of buying a light for a 3x3 tent that has gaps allowing for ventilation. Any thoughts?

I've just done exactly what you're thinking about doing.. I grow in a 2x4 tent and found the lights made for that size tent to be miserably small - and the ends of the tent never had enough light for anything. Took me a long time to find one but I looked for the DIMENSIONS, not the size of tent the light was "made for" ... and wow.... now I have a tent that measures 24" x 48" and my light measures 21" x 33" ... and to add to the wonderfulness, I was able to go from 200W to 450W - the DLI is perfect and my plants are super happy! I WILL tell you that the one thing you need to watch out for, if you do what you want to do, is the heat will go up quite a bit in your tent - so just allow for that, expect it and have a plan on how to deal with it if need be. I, personally, couldn't be happier with my decision! Good luck!

Siempre la intencidad disminuye hacia los lados. La luz es mas intensa en el centro. Mide la intensidad de la luz sobre la izquierda y la derecha deben ser iguales. Suerte

If you have a 2 ft tent put your light all the way to 1 side and measure on opposite side would be the same as having light centered in a 3ft tent. Know what i mean vern

Marshydro FC oder FC-E Lohnt sich der Mehrpreis der FC Serie im Vergleich zur FC-E Serie? Auf dem Papier ist der Unterschied ja eher marginal.

Can I switch my lighting schedule ?Hello everyone. 1st grow here. I'd like to swap my lighting (automatic plants) from [4am:midnight] to [4pm:noon] just to keep the temperature a little higher at night. Is it doable while not hurting the ladies or should I shift it an hour per day to change the cycle ? Thanks !

1 inch seedling under a humidity dome sprayed with water in a 24x24x36 Vivosun tent. I’m using a mars hydro ts 600 watt led which is 21 inches above my seedling (small tent). Do I downgrade to my 150 watt ufo light until I can do LST? This mars led is definitely warming up things

Eyeball and advise on my set up, and is this seedling stretching?Is my set up good until my humidifier comes? (using inflow air from in-line fan with a tray of water for humidity for now). I set up an additional light because I was concerned that this bad boy was stretching and want to provide some extra light for lower canopy later.

Longer Light Cycle - Mid Bloom Is changing the light cycle of an autoflower from 18/6 to 20/4 in mid flower too stressful? Doing so would bump my DLI enough to keep my existing light through harvest. She sleeps like clockwork but less so now in mid flower. Will she adjust in a couple days to a longer day?

Anyone affiliated with Mars Hydro? Very disappointed with customer service My TS 1000’s controller/driver crapped the bed. Contacted customer support, told them the issue, they diagnosed based on videos i send, and was told they were sending replacement parts. 2 weeks later, no email confirmation and no reply to my previous 2 emails sent a week apart.
